Class based instantiation mechanism can cause huge delays when booting. For example: when CONFIG_SENSORS_LM75 option is enabled for omap4-sdp board - it introduces 5-6 ms boot delay. It's not recommended to use this mechanism with embedded I2C, so disable it by leaving I2C adapter "class" field undefined (remove I2C_CLASS_HWMON).
